One image for all objects
You can get there with UV projection.

Select all bricks and switch to Edit Mode
Get in front view (View &gt; Viewpoint &gt; Front)
Select all vertices and go UV &gt; Project from view
Rearrange your UV map




Useful hack:
• Use a BW logo with black background
• Set the image to clip (so it doesn't repeat)
• Use MixRGB node to control the colors inside Blender
